In the past five days, Yichen has already had a plan, after a year of intermittent experiments, his "Fire Domain" sealing technique fragments have been almost tested, hundreds of fragments, most of them, in the continuous experiments, Yichen has already understood the role.

There are still some that can't be tried, some because the structure is incomplete, and some of the effects can't be completed. The effect of these fragments, Yichen has already guessed according to the structure and layout of the entire seal. There are only two uncracked fragments left, and these two fragments are the two largest of the hundreds of fragments, and they are also the two that Yichen has the most clueless.

However, in the past year, the growth of Yichen Sealing Technique is still considerable, and after many attempts and analysis of the entire sealing technique, Yichen guesses that the first fragment is the part of the "Fire Domain" about how to generate flames, and the second fragment is about how to transform natural energy.

And Yichen also has a general direction on how to study, but to complete this step, he needs the help of the others in the enchantment class.

There was exactly a five-day holiday, and Yichen arrived at the enchantment class early in the morning and gathered all the sealing masters in the village again. Unlike last time, this time everyone heard that Yichen had something to do, and they came over without much hesitation.

After everyone arrived, Yichen spent a full hour explaining to everyone that his thoughts on the "Fire Domain" sealing technique, his research ideas, and the general test results over the past year or so were of course only the results of the direction, and the real knowledge could not be taught casually, and there were also confidentiality regulations within the village.

Everyone was shocked when they heard this, knowing that most of them were still studying B-level sealing techniques, similar to Suwon and Fenji, which had already reached A-level sealing masters, were also still considering A-level sealing techniques. As for the S-class, although they have seen it, they have no clue at all, which is like Yichen, who is so bold to split the S-class sealing technique, and the result is that he has really studied something.

Yichen's main identity is now a member of the fifth class, but the miraculous thing is that his job in the enchantment class has not been canceled, in fact, he is still receiving the salary of the enchantment class every month, and the materials he used to study the sealing technique are all provided by the enchantment class. This was unanimously decided by the upper echelons of the enchantment class, and they felt that Yichen's sealing skill level would surpass them sooner or later, and it would be a good thing for Yichen to have more favors towards the enchantment class.

No, if nothing else, the research ideas that Yichen just spent an hour describing are worth the monthly salary paid to Yichen.

In the end, Yichen said that there were still two fragments of the sealing technique that had not been cracked, and after guessing what they were all about, the entire enchantment class went crazy. Everyone is not stupid, as long as you imagine for a moment, once the principle of the two fragments is analyzed, how much impact it will have on the entire ninja world.

Of course, it is not so easy to fully analyze it, and as a member of the Uzumaki clan who developed this sealing technique, it should not be possible to fully analyze the principle of transforming natural energy. Otherwise, the Vortex Clan would have already had a method of immortal cultivation.

But even if you don't understand the principle, as long as you can successfully convert natural energy through experiments, that's enough. Maybe you can find some forbidden art out of it.

So everyone put down their work and discussed the two fragments collectively. This matter was not accidentally reported to Onoki, if nothing else, just because Onoki's sealing skills are not low, he should be pulled into the water.

Sure enough, when Onoki heard about this research project, he also took part of his time to participate in it every day. As one of the strongest people in the ninja world, Onoki's vision is still very broad, and he has made a lot of suggestions to the people who have studied it.

Yichen's vacation is not long, only five days, but the difficulty of cracking these two fragments is far beyond Yichen's imagination, five days is not enough for everyone to crack, in fact, in these five days, everyone even stays in the theoretical stage of discussion and design.

Everyone opened their minds and put forward all kinds of ideas. As a result, because there are too many ideas, the experiment time is too long, and the cost is too high, so that everyone has to sift through and select some ideas with high feasibility to try first.

Although he couldn't participate in it from beginning to end because of the mission, Yichen still gained a lot, and Onoki personally made the decision and gave Yichen a reward for an A-level task. The contribution value of the reward is 5,000 points, and Yichen's short-term goal has been achieved at once.

Without a moment's delay, Yichen immediately redeemed the perceptual ninjutsu he had in mind.

Different from combat ninjutsu, perceptual ninjutsu belongs to the type of ninjutsu that is prepared before the battle, and the requirements for the speed of sealing are not high, and it is the kind of ninjutsu that is particularly easy to use, so the price is also expensive. After getting the ninja, Yichen returned home and began to read. Due to the study of ninjutsu and sealing knowledge over the years, Yichen's theoretical level has been improving rapidly, so there is no difficulty in understanding this perceptual ninjutsu.

After understanding the principle of casting, Yichen began his first practice, and as Yichen expected, the most test of perceiving ninjutsu is mental power, which is what Yichen is good at. So the first attempt was successful, and this is the first time in five years that Yichen has learned something so smoothly.

After Yichen finished sealing, he pointed a finger on the ground, and then, according to the description in ninjutsu, with the assistance of Chakra, Yichen's spirit spread along Chuck's position to all directions.

It's a magical experience, like having an invisible hand touching around you, and at the same time feeding back what you touch to your brain, which then assembles it into a scene.

The process was actually very fast, and within a few seconds of Yichen casting his ninja, he probed the surroundings.

But this ninjutsu also has a flaw, that is, it can only detect things that have life, or things that have energy. In Yichen's perception, there are many lifeforms around, and most of them have very small vitality. It's like it's depicted on paper in a very light color, and you can't see it if you don't look closely.

There are a small number of lifeforms that are very large, and they are like small suns, so that the images that Yichen perceives begin to shake. Yichen knew that these were ninjas, and these little sun-like things were chakras in the ninja's body. After trying the methods recorded in ninjutsu, Yichen no longer stared at these large light sources, but deliberately avoided them.

After practicing like this for a long time, watching these light sources move back and forth, Yichen feels very novel, from time to time some light sources break into Yichen's perception range, and from time to time some light sources leave Yichen's perception range.

But what is common is that none of these light sources seem to respond to their perceptions. It's a good thing, the more than 10,000 contribution points are worth it.

Yichen's mental power is very strong, and he has been playing by himself in the room for a long time, and he doesn't feel tired.

Yichen exited his perception, then went out, walked around, observed the living forms around him, and compared them with the images he perceived, so as to judge the scope of his perception. And the distance and direction in reality correspond to the perceived distance and direction.

It didn't take long for Yichen to fully master this perceptual ninjutsu. Another skill was put into storage, and Yichen was a little excited.

But it's going to be too late, and there's a mission tomorrow, so let's rest first.

The next day, after the fifth class reassembled, Loess glanced at Yichen with some emotion, obviously he already knew that Yichen had made a big news in the enchantment class again. However, the ninja still attaches great importance to intelligence, so he didn't dig deeper, but took the three of them to choose a mission as usual.

Instead, Yichen said to the other three people in the fifth class: "Yesterday I learned a perceptual ninjutsu, the perception range is about 100 meters, and if the direction is limited, the limit perception can almost reach 300 meters." Today, let's take on a task that can use perceptual ninjutsu. "Yichen told his companion that there was a reason, and it was unwise for the holy companion to conceal his ability during the battle, which would make everyone's cooperation fail.

Shinohara was a little speechless after hearing this, even if he was a physical ninja, he was annoyed when he heard Yichen's words. How did you learn a ninjutsu again? Is it that easy to learn ninjutsu? Good guys, or perceptual ninjutsu! In other words, where did you come from to contribute, and where did you learn it?

I can't learn any of them except the three-body technique now, and the three-body technique can only be used, and the possibility of actual combat application is too small.

Tian Nai is also a little envious, in the task during this time, Shinohara, as a power type, is the main attacker of the team, with the greatest effect, and the effect of Yichen ninjutsu output, although the effect is not very good, but it can often involve most of the enemy's mind, so that he can't let go of his hands and feet. It's just himself.,As a speed-type ninja.,You can only harass with kunai on the side.。

Now that Yichen has learned to perceive ninjutsu again, his role in the team is even greater, but his progress is not so obvious.

This is actually not to blame Tian Na, the speed ninja is not without an advantage, but in the early stage, when the speed does not grow to crush the opponent, the advantage is too small, one-on-one, you can do it You can't help the enemy, and the enemy can't help you. But when fighting in a teamfight, the enemy can completely ignore you and concentrate on the other two.

If the enemy encountered by the fifth squad is not strong enough, then it can be defeated without using the speed advantage. If the enemy's strength is strong, then the opponent's speed is already much faster than that of Yichen and Shinohara, and Tian Nai's advantage compared to the other party is not obvious.

So for the past year, Tian Nai has been saving money, the purpose is to exchange for the instantaneous technique, if you can learn the instantaneous technique, then you can better play the speed advantage. In the face of a ninja who is nimble but may burst into his side at any time, no one dares to relax. This is also the method I learned from the first mission, the middle shinobi named Takeo.

At that time, Takeo rushed directly in front of Yichen before he performed his ninjutsu, and if it wasn't for Tian Nai's premeditated speed raid, Yichen's ninjutsu would have been interrupted, and the rhythm of the next battle would have been completely controlled by the other party.

I don't know what Yichen is thinking in the hearts of the two, and I have already started to choose a task in a hurry. It didn't take long to choose a search mission.

In the mission description, there is a family whose child is missing, and the ninja is entrusted to find it.

To be honest, the disappearance of the child in this year is almost equivalent to death, if this happened in the village, it would be fine, after all, the security of the village is good, it is difficult to say where the child got lost and couldn't find his way home, in this case, there is no need to issue a mission, it may be brought back by a passing ninja.

But it happened in a small town quite far from the village, and that kind of place, leaving the town can be regarded as a place outside the law, and it is impossible for a child to find it back.

Yichen was also a little hesitant, but in order to test the effect of ninjutsu, he still chose this task. And the other three also wanted to see how amazing the perceptual ninjutsu that Yichen said.
